The starting price for the 2018 model year is $349,000, which includes the cost of the donor Raptor plus a tune of the 3.5-liter twin-turbocharged V-6 so that it delivers 605 horsepower and 622 pound-feet of torque, up from the stock 450 hp and 510 lb-ft rating.

The upgrade includes custom turbochargers, a high-flow exhaust system, a bigger intercooler, and full ECU tuning. For buyers with really deep pockets, Hennessey also offers an upgraded Brembo brake package, larger wheels, and interior upgrades for an additional $22,000.

The VelociRaptor 6x6 is available to order directly from Hennessey or through select Ford dealers. Just 50 are planned for the 2018 model year.
